Could you post the full stack trace? Have you checked whether your setupRender() method is really being called? If the page with these fields and methods isn't the one being requested, the setupRender() method won't be called. In addition, if the only place you use the collection field is in getSource(), you could get the collection from inside getSource() directly, without using setupRender() for that. I thought my properties would be binded by now These other fields are completely unrelated to your problem. -- Thiago H. de Paula Figueiredo - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
RE: query a collection for a page
oops... I meant to say year, league, season are all null at the time of the query in getSource()
RE: query a collection for a page
Well my code is based on the hope that my properties year, league, season will bind in time in order to perform a successful query. Am I performing the query in the wrong place?
query a collection for a page
Hi Folks, I have a page that renders a collection in a grid. A hibernate collection... @Persist @Property private Collection collection; @SetupRender public void setupRender() { beanType = PlayerStats.class; collection = playerStats = new ArrayList( TynamoUTIL.loadCollectionByYearAndLeagueAndSeason( hibernatePersistenceService, year, league, season, PlayerStats.class));// I know its hoakey for now grid.reset(); } but my getSource is giving me an NPE public GridDataSource getSource() { return new CollectionGridDataSource(collection); } I thought my properties would be binded by now @Property @Persist(PersistenceConstants.FLASH) private Year year; private ArrayList years; @Property @Persist(PersistenceConstants.FLASH) private ELeague league; @Property @Persist(PersistenceConstants.FLASH) private ESeason season; Am I doing something wrong ? Where/How do I query a collection for any given page ? I thought this was the right way to do this. Thanks for any tips.
